Attribute points are obtained by leveling up the class, not the job. In fact, you start obtaining them before you can even unlock a job, and keep obtaining them even if you were to level up without using the soul stone, so I can see why they can't make them job-related.
However they said that they're working on a way to make it easier for us to re-set them at will. Not something I'd do every time I swap from SMN to SCH, but hey, some people may be just perfectionist enough to do it.
Personally, I put all my ACN points into Piety. Least I know it will help both SMN and SCH.
